Voltage dips and short interruptions simulate a reduction of the power supply voltage for a certain period of time. Four different test levels are required as per IEC/EN 61000-4-11.

The V 4780 Series of tapped transformer are used to simulate power supply failures such as voltage dips and interruptions providing taps with 40 %, 70 %, 80 % and a direct output with 100 % of the nominal mains supply voltage. Depending on the model the taps are selected manually or by means of the 0-10 V DC signal provided by the test generator.
